 Adoxus Bowringii, Baly, Journ. of Entom. i. p. 27. 



Ovatus, valde convexus, nuceus, pilis adpressis obscure fulvis 

 indutus ; thoracis plaga obtrigonata, elytrorum maculis 7, 

 metacoxis pleurarumque plaga nigris. 

 . Var. A. Thoracis plaga elytrorumque maculis nonnullis obso- 

 letis. 



Long. 2\ — 3 lin. 



Hab. Malacca, Borneo, Penang ; also Birnaah, Gambodia, and 

 Northern China. 



Ovate, very convex, nuceous ; body covered with obscure ful- 

 vous adpressed hairs ; an obtrigonate patch in the centre of the 

 thorax, seven spots on the elytra, a patch at the apex of each 

 pleura, and the metacoxag shining black. Head distinctly punc- 

 tured ; epistome triangular, separated from the face by a grooved 

 line; on either side, just above the insertion of the antennae, is a 

 slightly raised smooth tubercle ; eyes black. Thorax subglobose 

 above, covered with fulvous hairs, which are shorter and less de- 

 pressed than those of any other part of the body ; sides regularly 

 rounded; surface deeply punctured, puncturing crowded and 

 rugose on the sides, somewhat more scattered on the disk, the 

 middle of the latter covered by a large obtrigonate black patch. 

 Elytra oblong, sides parallel, slightly narrowed near the apex, the 

 latter regularly rounded, dehiscent at the sutural angle ; above 

 convex ; each elytron with eleven sulcate striae, the first abbre- 

 viated, each stria impressed with a single row of irregular punc- 

 tures, interspaces somewhat raised and subcostate towards the 

 lateral margin, their surface covered with distinct punctures, which 

 render those of the striae confused ; a large subbasal rotundate 

 spot, a common bilobate patch at the middle of the suture, an- 

 other, larger and oblong-ovate, placed behind the middle, and 

 a small spot placed externally to the humeral callus, shining 

 black. 



This insect varies in the number of black spots on the elytra. 

 The patch on the thorax is also sometimes wanting. A second 

 species, A. nigripes, mihi (Journ. Ent. i. p. 28), is found in 

 Siam, from which point it ranges upwards (like the present in- 

 sect) as far north as China. It in all probability is also found 

 in Malacca, although I have not as yet seen specimens coming 

 from that locality.
